Condiciones de salud que pimienta de cayena puede ayudar a apoyar.
Cayenne pepper/capsaicin has been evaluated in clinical trials for functional dyspepsia. A double-blind RCT found 2.5 g/day red pepper powder significantly reduced epigastric pain, nausea, and bloating versus placebo in patients with functional dyspepsia. Capsaicin also stimulates gastric motility and enzyme production.
Cayenne pepper is rich in capsaicin, carotenoids (beta-carotene), and vitamin C, all established antioxidants. Capsaicin itself has demonstrated antioxidant properties in multiple studies, scavenging free radicals and reducing oxidative stress, with supporting human data from cardiovascular research.
Multiple human trials show capsaicin, the active compound in cayenne pepper, reduces energy intake and suppresses appetite, partly by lowering ghrelin and altering sensory desire for fatty and sweet foods. Effects are dose-dependent but modest. A PMC-published systematic review (2017) confirmed appetite suppression is most evident with oral versus gastrointestinal-only delivery.
Topical capsaicin is supported by multiple RCTs and a positive meta-analysis for osteoarthritis pain relief. A systematic review and meta-analysis published in Phytotherapy Research (2024) confirmed topical capsaicin significantly reduces osteoarthritis pain. A 0.0125% gel was effective in a placebo-controlled trial of 100 patients over 4 weeks.
Topical cayenne pepper cataplasms and capsaicin creams have been used in traditional medicine and evaluated in controlled studies for back pain. A PMC study specifically used cayenne pepper cataplasm for back pain and rheumatism. Capsaicin cream is used clinically for lower back pain via the same substance P depletion mechanism as other musculoskeletal pain.
Higher fibrinolytic activity documented in Thai populations has been attributed to regular daily cayenne pepper consumption. Capsaicin promotes fibrinolysis (clot dissolution) and has mild anticoagulant-like properties. ScienceDirect cites this population-level fibrinolytic observation as a noteworthy finding attributed to cayenne intake.
A 2026 meta-analysis of 13 RCTs (n=821) found capsaicin supplementation significantly reduced diastolic blood pressure (−1.62 mmHg), though the finding was dependent on a single study and rated as low-certainty evidence. Mechanistically, capsaicin induces vasodilation via TRPV1 and CGRP release. Overall human RCT evidence is modest.
Human evidence for capsaicin's effect on blood glucose is mixed. An OGTT study in 12 healthy volunteers showed capsaicin increased plasma insulin and attenuated blood glucose. However, a meta-analysis of 14 human trials found no significant effect on fasting blood glucose versus placebo. Animal studies consistently show benefit but human data are limited and conflicting.
A meta-analysis of RCTs in patients with metabolic syndrome found capsaicin significantly reduced total cholesterol and LDL-cholesterol. A separate RCT (n=42) found 4 mg/day capsaicin for 3 months raised HDL and lowered triglycerides. A 2026 meta-analysis of 13 RCTs also found a significant total cholesterol reduction, though rated as low-certainty evidence.
Capsaicin inhibits pro-inflammatory mediators including IL-1β, IL-6, and TNF-α in vitro and exerts anti-inflammatory effects through TRPV1-mediated pathways. Human evidence is primarily mechanistic and observational; robust RCT data specifically measuring systemic inflammatory biomarkers like CRP in response to oral cayenne are limited.
Topical capsaicin is among the most evidence-backed non-opioid topical analgesics for chronic pain conditions. Cochrane reviews, multiple RCTs, and a prescription-approved 8% patch support its use for postherpetic neuralgia, diabetic neuropathy, and musculoskeletal pain. The mechanism is well-characterised: C-fibre desensitisation via substance P depletion.
Capsaicin promotes vasodilation and increases peripheral blood flow via TRPV1 activation and release of vasodilatory neuropeptides. Observational data from Thai populations consuming daily cayenne link regular intake to elevated fibrinolytic activity. Cayenne has also been traditionally used to improve peripheral circulation.
Topical capsaicin has been studied for fibromyalgia-related muscle pain in controlled trials. A pilot study published in Seminars in Arthritis and Rheumatism (McCarty et al., 1994) and several subsequent double-blind trials showed significant pain reduction from topical capsaicin application in fibromyalgia patients.
Intranasal capsaicin has been evaluated in double-blind controlled trials for cluster headaches with significant results, and weaker evidence supports its use for migraines. Topical capsaicin has also been studied for cluster headache and trigeminal neuralgia. The mechanism involves desensitisation of trigeminal C-fibres.
Multiple RCTs and a meta-analysis in the British Journal of Nutrition confirm capsaicin supports modest weight loss in overweight and obese subjects through thermogenesis, increased fat oxidation, and appetite suppression. Effect sizes are small and meaningful only within a controlled-diet context.
Observational data show regular chili pepper consumption is associated with a 13% reduction in all-cause mortality and lower risk of heart attack and stroke. Capsaicin has demonstrated effects on cholesterol, blood pressure, fibrinolytic activity, and vascular inflammation, though RCT evidence for hard cardiovascular endpoints is limited.
Capsaicin activates TRPV1 receptors in insulin-sensitive tissues and has shown effects on insulin secretion and glucose uptake in human studies. An OGTT study in healthy volunteers found oral capsaicin increased plasma insulin and attenuated post-load blood glucose. Animal data are robust; confirmatory human RCTs are limited.
Capsaicin has been specifically evaluated as a multitarget intervention for metabolic syndrome, addressing central obesity, insulin resistance, dyslipidaemia, hypertension, and chronic low-grade inflammation. A 2022 PMC review and a meta-analysis of RCTs in metabolic syndrome patients both document meaningful effects on lipid profiles and cardiometabolic risk factors.
Capsaicin consistently increases resting energy expenditure and fat oxidation in human studies by activating brown adipose tissue (BAT) through TRPV1 signalling. Studies typically report a 4–5% increase in metabolic rate, enhanced lipolysis, and reduced fat accumulation with sustained capsaicin intake.
Intranasal capsaicin has been evaluated in controlled trials for cluster headaches (with double-blind support) and for migraines (with weaker evidence). Desensitisation of trigeminal sensory fibres is the proposed mechanism. PeaceHealth notes double-blind trial support for cluster headaches and weaker evidence for migraines.
Topical capsaicin is used for musculoskeletal pain including muscle soreness, operating via substance P depletion in peripheral nociceptors. A PMC study confirmed topical cayenne cataplasm produces measurable vasodilation and local anti-inflammatory effects in muscle application sites. Traditional herbalism also documents cayenne for muscle aches.
Topical capsaicin is clinically established for neuropathic pain, including diabetic peripheral neuropathy and postherpetic neuralgia. It desensitises C-fibre nociceptors by depleting substance P. Cochrane reviews rate evidence for low-concentration topical capsaicin as mildly positive for neuropathic pain, and high-concentration (8%) patches are prescription-approved.
Two 6-week RCTs (n=241 total) found topical capsaicin cream superior to placebo for relief of psoriasis symptoms including scaling, thickness, erythema, and pruritus. An evidence-based review of botanicals for dermatologic conditions cited these trials as supporting clinical use of topical capsaicin for psoriasis.
Multiple double-blind trials demonstrate topical capsaicin cream provides significant pain relief in rheumatoid arthritis by depleting substance P at peripheral joint nociceptors. PeaceHealth's evidence-based summary and Cochrane-referenced literature confirm this indication, with topical capsaicin used as an adjunct to standard RA therapy.
Cayenne pepper contains capsaicin and capsaicinoids that irritate then desensitize TRPV1 nociceptors in nasal mucosa, reducing neurogenic nasal congestion. Clinical studies of intranasal capsaicin (the active constituent) document ~60% reduction in nasal airway resistance with benefit lasting >4 months. Traditional use of cayenne across multiple cultures for sinus clearing is extensively documented.
Capsaicin is among the best-characterised dietary thermogenic agents, activating brown adipose tissue (BAT) through TRPV1 and increasing resting energy expenditure. Human RCTs including a double-blind placebo-controlled study (n=40, 9 mg/day capsinoids) confirmed increased BAT vascular density and resting energy expenditure in overweight individuals.
Contrary to popular belief, capsaicin at low doses appears gastroprotective, stimulating mucus and alkali secretion and increasing mucosal blood flow. An RCT of 84 volunteers showed low-dose capsaicin protected the stomach lining against alcohol and indomethacin damage. However, one clinical study found no difference in duodenal ulcer healing with 3 g/day capsicum versus controls.
Cayenne pepper is a longstanding traditional remedy for cold and flu, used to break up mucus congestion, induce sweating (diaphoretic action), and support the immune response. Its vitamin C and beta-carotene content provide antioxidant support. Clinical RCT evidence for cayenne specifically reducing cold or flu severity or duration is absent.
Cayenne has traditional documentation for use in diarrhea and gastrointestinal distress. URMC Rochester's herbal database notes cayenne may act as a digestive tonic. High doses of cayenne can paradoxically worsen diarrhea due to intestinal irritation. No clinical RCTs confirm anti-diarrheal efficacy.
Cayenne pepper has traditional use as a diaphoretic (sweat-inducing) agent, used to support the body during fever. It is documented in traditional herbal medicine to raise skin temperature and stimulate sweating, which is considered to aid in fever resolution. No clinical RCTs confirm antipyretic efficacy.
Cayenne pepper has a well-documented traditional use as a mucolytic and expectorant, stimulating the release of mucus from the respiratory passages and aiding its clearance. This is attributed to capsaicin's irritant action on the respiratory mucosa, which triggers secretory reflexes. Clinical RCT evidence specific to mucus clearance is lacking.
Traditional herbal medicine documents cayenne's use for nausea, and the PMC review of Capsicum annuum lists postoperative nausea and vomiting among the conditions for which capsaicin has been used. Nausea is also a potential side effect of excessive cayenne intake, creating a complex, dose-dependent relationship.
Cayenne pepper's active compound capsaicin is an analgesic and anti-inflammatory agent. Applied to the throat via gargle, capsaicin temporarily desensitizes pain-signaling nerve endings (TRPV1 receptors), reducing sore throat pain. Its use as a gargle for sore throat is a longstanding traditional folk remedy in North America. No direct RCTs for acute sore throat have been completed, but the pharmacological mechanism is well-established.
Cayenne pepper (Capsicum annuum) is traditionally recommended by herbalists for spider veins and varicose veins due to capsaicin's circulation-promoting and anti-inflammatory effects. It appears in historical and contemporary herbal protocols for venous insufficiency. Evidence is primarily traditional and mechanistic rather than from dedicated clinical RCTs.
Cayenne/capsaicin has traditional use for toothache, applied topically to numb localised dental pain through substance P depletion and C-fibre desensitisation. The ScienceDirect Capsicum overview and URMC herbal database document this traditional use. No controlled clinical trials in dental pain specifically have been identified.
Cayenne pepper has extensive traditional use for cough, bronchitis, sore throat, and respiratory congestion. Capsaicin's irritant properties stimulate mucosal secretions and airway clearing. Clinical evidence for these specific upper respiratory indications is limited, though nasal capsaicin has been evaluated for rhinitis.
Traditional medicine documents cayenne's use in wound healing, and the PMC review of Capsicum annuum lists wound healing among traditional applications. Capsaicin promotes local blood flow and has antimicrobial properties in vitro. Controlled clinical evidence for cayenne in wound healing is absent.
